Another way in which extra JS code affects memory usage is the start-up cache, which in a new-ish profile on my Mac is 7.5 MiB. I've included a list below showing all the entries in the start-up cache and how much space they take. (All the 'jsloader' ones are XDR encoded bytecode, which is why they're a lot bigger than the original source code.) If anyone can identify entries that could be lazily loaded, please speak up or file bugs.
